Well I started with a uber modded QB78 and added lots of stuff too it.
it started has a QB78 .25Cal that shot 950fps it was a ton of fun hit like a truck
would have made a great hunting rifle but I had other plans.

Sold the .25 LW barrel and bought a .177 LW barrel
A extended bolt probe, a bi-pod a AR2078 Thunb stock and painfully cut it.
I have instal a crazzy Scope on this its a copy of a great scope and it works great
for a copy let me tell you.
Its a ZOS 10-40X60 SF with big wheel and I have a sun shade for it, but with curent set up
it does not fit.

still lots of finishing to do on it and some tuning I will tune it for 780FPS with JSB's 8.44G
and use it for FT if I like how it shoots.

So I work on it today ajusted it too 780fps at 10m. I would have like too ajust it more but one of my lights on my crony light kit
just stop working and I was not even shooting at the crony and no I did not hit the crony.

so this is not a real test since 10meters is not all that far, but at 10meters I'm shoting pellets in the same hole shot after shot 10 in a row no problem.
it's very good and my fps do no change more then 10fps and that is one of the reasons I bought QbBob it's shot string is flat across the the board from 3000psi
too 1200psi, this is a wonderful FT airgun, I have almost 1000$ invested in it,

I know I could have bought a Hammerli AR20 and would have shot about the same, but there is something I like of having something custom and from a cheap 125$
starting point,

and yes I will be selling some of my other great airguns to pay for this setup. Disco will be sold soon.

Congrats on your FT rig... FT is a perfect extension of the airgun shooting experience... Take full advantage of any opportunity to get out and shoot at these events..
I've been shooting with a highly customized QB for a few years now and if I did my part, that rifle allowed me to be fairly competitive along the way..
